from which is regulated by a `bermostetic'- ally controlled damper Y The clnef objects of my invention areto i rovidea sim )le and eticient a i ratns for the purpose in view so that its operation can be readily understood and easny managed by an unskilled person.

Further advantages lie in its superior efficiency,1 the maintenance of a substatitially uniform temperatureend .the arrangement `of the parte which give easy access to all ortions of the structure.

n the furtherance of these and other objects and advantages l prefer to construct 4:my improved poultry brooderin tnfc super` imposed removable sections rectangular in form, placing the warming appliance in the lower section and utilizing the upper for the young chickens. The sections are kept in relative position by cleats at the corners secured to the up )er section. 1 I prefer to cover the top of the Jrooder with sashes set with glass; an arrangement which gives an abunf' ance of light, thus promoting the health o f the poultry und tending to prevent the spread of diseases andthe propagation .of vermin which so frequently infest places where poultry are kept in numbers., This construction permits of ready inspection of every portion of the upper compartments and the sashcs may be raised for purposes of ventilation or removed altogether to clean the compartments.

In the drawing, Figure. 1 is a longitudinal section of my improved poultry broeder, F ig. 2 is u hormontcl section of the same., and Fig. 3 is a fragmentary view, enlarged, showing the upper end of the lower section of t-hn n ir pine and cap in vertical section.

f ltcierring to the drawing, A represents the lower section and B the upper section. The

lower section A has a floor a and is divided by a vertical partition mt'o two com artments a,a. Near the upper part o the rear com artmcnt as is n shallow closed metal tan or reservoir C for water which is preferably constructed of galvanized iron and has a horizontal area approximating that of the compartment.

The upper section B is likewise seperated into' two compartments by a are tition b* und has a floor b. The center o the floor of the rear upper compartment b sperfoi-ated by s pipe d"vrhxch communicates with the air space above the water reservoir in tho compartment as and affords a passage for the Warm air'to ascend v'to the said compartment b. The open end of the pipe is covered by'a. screw cap, or cover d, provided with perforations dl. Arranged above said pipe d* at a short 'distance from same, is an inclined 'Fue pipo d which communicates with the external air through a vertical extension d.
